Q80021311 - After updating ARC-8050 boot, firm, and mbr0 bin files to 1.52 version using ethernet port, the unit can't boot up during the reboot, all three LED flashing with LCD panel shown "-" only.

It can fix by bootup from thunderbolt capable system. This is an issue for updating the some old version f/w of ARC-8050 to 1.52 using forced power on ARC-8050 without linking to thunderbolt capable system.
